Small fold – big role: A tissue fold known as the cephalic furrow, an evolutionary novelty that forms between the head and the trunk of fly embryos, plays a mechanical role in stabilizing embryonic ...

Birds and mammals use the same genes to build their face, but deploy them differently in time and space. Cells and evolutionary change: The undifferentiated facial mesenchyme emerges as an essential ...

Have you ever looked at a human embryo and thought, “That kind of looks like a fish”? If you haven’t, you might be surprised to learn that, in a way, we all begin our lives like this. The idea that ...

Amphioxus, as a basal chordate, offers an insightful window into the evolutionary origins of vertebrate development. Its embryogenesis, characterised by the formation of a notochord, neural tube and ...

Embryonic germ layers are the fundamental organizing principle in animal development. They provide the structural basis from which tissues and organs arise. During early embryogenesis, cells divide to ...
